To all whom it may concern:

Be it known that I, SAMUEL K. Dnxxis, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hay-Loaders, of whichthe following is a specification.

My invention relates to hay loaders of the swinging rake type, andconsists in improved means for imparting to the rakes a combinedlongitudinal and rising and falling movement; in the manner of mountingthe rake heads at the lower ends of the rake bars; in means forsupporting the lower end of the main frame upon the ground, and inproviding a floating extension for the elevator deck at its lower end;the object of my invention being to construct a machine having fewparts, strong, durable and clii cient in operation. These objects areattained by means of the mechanism illustrated by the accompanyingdrawing, in which-- Figure 1 is an end elevation of a hay loader havingmy invention forming a part thereof; Fig.2 is a side elevation of Fig.1; Fig. 3 is a detached top view of part of the rake bar controllingmechanism; Fig. 1 is a detached detail drawing of part of the draftframe and illustrating the manner of connecting it with the axle of themachine; Fig. 5 is anend elevation of Fig. 4; Fig. 6 is a detacheddetail drawing of part of the rake bar control-ling mechanism andillustrating its mode of operation; Fig. 7 is adetached detail of partof Fig. 6, shown partly in section; Fig. 8 is a side elevation of theadjustable wheel support at the lower end of the elevator frame; Fig. 9is a bottom view of Fig. 8, partly in section; Fig. 10 is a frontelevation of part of Fig. 2; Fig. 11 is a detached detail drawingrepresenting the manner of mounting the rake heads at the lower ends ofthe rake bars; and Fig. 12 is a detached detail of part of Fig. 11.

The same referencecharacters designate like parts throughout the severalviews.

The loader is mounted upon carrying and traction wheels 1 mounted uponopposite ends of an axle 2.

Theupper ends of the vertical members are turned outward and securedthereto by castings 11, to which are secured the forward ends of framemembers 12 that extend rearward in substantially a horizontal plane, andsecured to their rear ends are vertical frame members 13.

1 1: represents side members of the elevator frame, having their middleportion secured to the forward ends of frame members 12 and to castings11, the said frame members being inclined upward from rear to front ofthe machine and having their lower ends secured to the lower ends of thevertical members 13; and 15 represents brace members having their rearends secured to said frame members 14 and their forward ends providedwith eye portions 16 that receive the outer ends of the axle; and 17represents cotter keys that retain them in place thereon.

Secured to the lower ends of the side members of the elevator frame arecastings 18 that are provided with vertically arranged bearing surfacesupon their outer sides having central transverse openings therein andprovided with radially aranged corrugations, and adj ustably se cured tosaid castings are arms 19 provided with boss portions 20 having radialcorrugations 21 upon their inner surfaces adapted to engage with thecorrugated surfaces of castings 18; the parts being secured in adjustedrelation by means of bolts 92. Journaled at the lower ends of the arms,upon their inner sides, are supporting wheels 23, having outwardlyextending hub portions that are surrounded by and bands 25 forming l tof said arms. The wieels are also provided with annular concentric ribs26 upon their outer sides, and the lower ends of the arms are turnedinward within the ribs in a manner to pre vent hay from winding upon thehub of the wheel; and 2'! represents inwardly projecting wings arrangedupon the edge of the arms in a manner to shield the upper forwardperiphery of the wheels.

The lower end of the elevator may be adjusted toward or from the groundby means of the adjustable arms 13 The elevator frame is provided willseries of transverse bars having their 01 posite ends so cured to thelower sides of the side frame members, and represents deck memberssecured to the transverse bars.

Below the transverse frame member, at the lower end of the elevator, isarranged a board 30 extending transversely across the frame andsupported at its opposite ends by means of ba s 31 secured to the loweredges of the side iraine members, the board being free to slide upward tider the deck of the elevator to itCOUlllillOCii e itself to the varying masses of hay bein operated upon, the board being a floatingextension of the deck at its low'r end.

Journaled in bearings forming of castings 11, is a transverse shaft ingsecured to opposite ends thereof, outs of said castings, cranks 8 1:.Inside of said bearings, and secured to the shaft, are sprocket wheelsand 56 represents a sprocket wheel secured to the axle and operative totransmit motion therefrom to said transverse shaft means of sprocketchains 3?. Secured to the rear ends of frame members 12 are castings 38,having transverse bearings 39, in which are journaled a pair of parallelrock sh iLS 1-0, having secured to opposite ends thereof intermeshinggear se ments ell, the gear segments being prmuued with crank arms L2,to which are secured the rear ends of levers e3.

l i represents rake h rs that are arranged in two above the elevatordeck and provided with depend ng teeth -l5 spaced apart and secured tothe lower sides of the bars and operative to move the hay upward uponthe elevator deck when the rake bars are moved longitudinally relativethereto.

46 represents a bar arranged transversely across the upper end of theelevator above the rake bars, and journaled thereto, at opposite endsthereof, are flanged rollers 4.7 that roll upon fixed tracks iponopposite sides of the elevator. The rake bars of one of the aresuspended from bar by means of brackets 49, transverse bar 50 beingplaced above the rollers in a manner to limit an upward movement of therake gangs.-

I l l 1 51 represents a like transverse bar arranged lower down upon theelevator and upon which are secured other gangs of rake bars by means oflike brackets. The lower ends of the rake bars in each gang areindependently connected with the rock shafts etO, one of the gangs beingconnected with one shaft and the other gang with the other siaft, theconnecting means being a series of resilient bars 52, having their upperends secured to one of the rock shafts and their lower ends havingsecured thereto a fork member 55, in which is journaled, upon atransverse pivot, a roller 54: that engages with a brac :et 55 securedto the upper side of the rake bar, the brackets permitting alongitudinal movement of the rake bars relative to the supporting bars52, and 56 represents short supplemental bars having one end secured tothe rock shaft upon the side opposite to that to which is secured thebars 52, and their opposite ends secured to said bars in a mannerforming a double connection between the bars 52 and the rock shafts.

rvi

it) the lower ends of the rake bars are secured clips 57, havingdownwardly extending ear portions 58 upon opposite sides thereof thatare provided with transverse openings therein that loosely receive arake head 59, having secured thereto depending resilient rake teeth {30,the heads being adapted to rock freely in their bearings, and 61represents clips secured to the heads between the ear portions 58 andhaving oppositely disposed wing portions that are adapted to contactwith the clips 57 in a manner to limit a rocking movement of the heads.

Pivotally connected with the frame members 12. upon opposite sides ofthe machine, are vertically arranged levers 62, having their upper endsconnected with opposite ends of the transverse bars 4E6 at the upper endthe elevator frame by means of pitmen 63, and their lower ends withopposite ends of bar 51 by inea s of pitmen Get; the lower ends of thelevers being also connected with the cranks at opposite ends of theshaft by means of pitmen 65, whereby a rotative movement of the shaftand cranks allows the levers to vibrate about their pivotal connectionsin a mannerto transmit a longitudinal movement to the separate gangs ofrake bars in an opposite direction through their connection therewith.The forward ends of the levers 555, that are connected at their rearends to the gear segments secured to the rock shafts, are slidablyreceived by bearing blocks that journuled coaxially with the pitmen uponthe cranks 34- whereby a rotative movement of the cranks causes thebearing blocks to slide upon the levers and transmit thereto a risingand falling movement at their forward ends, which causes the rock shaftsconnected with their opposite ends to rock in an opposite direction in amanner to alternately raise and lower the rake gangs connected therewithsimultaneously with their longitudinal movement, a result common to thisclass of machines.
